s2png 0.05 發布，將二進制數據轉換成PNG圖像
s2png將二進制數據轉換成有效的PNG圖像（如托管在Web上）和任何類型的文件。它支持加密輸出。
s2png ("something to png") version 0.05
usage: s2png [-h] [-o filename] [-w width (600) | -s] [-b text]
[-p password] [-e | -d] file
Store any data in a PNG image.
This version can encode files of up to 16777215 bytes.
-h display this message and quit
-o filename output the converted data (image or binary) to filename
-w width set the width of PNG image output (600 by default)
-s make the output image roughly square
-b text custom banner text ("" for no banner)
-p password encrypt/decrypt the output with password using RC4
(Warning: do not use this if you need actual security!)
Normally s2png detects which operation to perform by file type. You can
circumvent this with the following switches:
-e force encoding mode
-d force decoding mode</pre>
發布說明: 該版本增加了對FreeBSD支持以及PNG輸入無效的檢測，專用命令行開關來強制編碼和解碼模式, and an input file size check when encoding (you can currently store files of up to 16777215 bytes inside .png images). It fixes the issue that caused data corruption in the last few bytes of images of certain sizes that didn't have a text banner at the bottom. Code formatting has been improved, and a number of code comments have been added。
